As a Texas expat doing time in Rhode Island, I'm all for it - secede, union of states, something.
I'd actually like Texas to call for an article V convention, and move to dissolve the social pact between the states. It would dissolve Fed Bank, Fed Reserve, and every Fed Agency with it, to include Soc Sec. IRS, BATF, FBI, DOJ, national debt, all treaties ... gone. Probably have to figure out how to distribute the military, particularly the nukes. Requires 38 states to support it - might be tight. This would free up all the states, territories, district, protectorates to then re-form a new social contract with whomever they wish. In which case I think Texas might find 20-30 other likeminded states willing to just return to the original constitution and start over. My guess is if you got 38 states willing to dissolve, everyone at that point would be more willing to come to the table and rather than dissolve, talk about reform.
